Weird Taste in my Mouth

DaVina

So Im 3-4 DPO and all of a sudden I got this weird taste in my mouth and nothing is helping it go away. Ive been taking the same prenatal vitamins since I started trying to conceive. Im not sure what this taste is. My mouth is also very watery. Can anyone shed some light on what may be happening. Not AF(AF) is suppose to start on 7/14.
